Specification forming part of Letters Patent No. 146,527, dated January 20, 1874; application tiled f March 3, 1873. i

To all whom it may concer-n Be it known that I, WILLIAM HniLEs, of

the city and county of Albany, State oi" vation of a stove embodying the improvements in this invention. Fig. 2 is a sectional eleva` tion taken in the transverse. Fig. 3 is a vertical view taken at line No. l in Figs. 2 and 3. Fig. Amis a vertical sectional view of the fue pot and grate; and Fig. 5 is a plan view of the grate,`the lire-pot being shown in dotted lines.

My invention relates to certain improvements in the lire-pot and grate of heating stoves and furnaces; and consists, in one part, of a tire pot or box constructed with its lower end declining from front to rear, in 'combination with a horizontal gra-tc, pivoted and supported so as to operate both as a circular and a tilting grate, the object of this part of the invention `being to produce an opening at the front of the lire-pot, between the upper surface of the grate and the declining end of the fire-pot, through which the clinkers, ashes, Sto., may be removed, either by operating the grate in an inclined position or by the use of some instrument, or both. Another part of my invention consists of a fire pot or box constructed with its lower end declining from front to rear, and with a shelf or ledge projecting inwardly from the front portion of said declining lower end, in combination with a horizontal grate pivoted and supported so as to operate both as a circular and a tilting grate, the object of this part of the invention being to prevent the fuel from being packed down toward the front of the grate when the latter is being depressed in front or shaken for the purpose of removing the clinkers, 8vo.

f Another portion of my invention consists of a lire-pot constructed with its lower end declining from front to rear, in combination with a horizontal grate pivoted and supported so as to operate both as a circular and a tilting grate, having its rear portion within the irepot and its front portion projecting beyond the lower end of the re-pot in front, the obis the horizontal grate.

`ject ot' this part of the invention being to pre-` vent the escape of the fuel through the opening between the grate and declining end` of the fire-pot by preventing it from running over the edge ofthe grate.

To enable others skilled in the art to inake and use my invention, I will proceed to describe it in reference to the drawings and the letters of referenceinarked thereon, the same letters indicating like parts.

In the drawings, A represents` the base of the stove. B B are the outer walls of the lirepot section, forming the outer wall of the side nues G C. C C is a plate forming the inner wall of the same. D is the ire-pot. E is the y magazine for holding the fuel. F F are the walls forming the combustion-chamber above the lire-pot, and are made of metal, with door or window frames for holding mica lights.

In my invention I form the fire-pot `with a sloping or beveled lower end, a, Figs. l and 2, in sucha manner that when the grate Gr is arranged horizon tally there will be directly in front, between the front edge of the grate Gr and the lower edge of the lire-pot, a space, a', which, as it runsfroln the front toward and round the sides, will contract in width until wholly lost, as shown in Fig. 2. By thus beveling or sloping the said lower edge 'ot' the fire-pot, and having the grate preserved in its horizontal position,`the said space will atlord a ready means for the discharge of the clinkers that may be formed in the iire-pot from the front"of the same, which may be easily` doneby `shaking the grate and atthe Sametime tilting its fronta p grate, while the gradual contraction of the y said opening at the sides will permit but a small escape ot' the same proportionately with the size of the side portions of the said opening, and only the small clinkers and particles of fuel will be permitted to escapeat the sides, and the larger clinkers will be gradu-" ally worked toward the eXtreme front, to and out from the greatest depth of `space in the said opening. To prevent the fuel in the tirepot from escaping or falling directly down n the grate when being operated, I make on the A inner portion of the irepot, and with the terv Ininating lower beveled edge a, the ledge Aor shelf z, as shown. This ledge is of the greatest width at the front, where the opening m is the largest, and gradually narrows as it runs from the front to the sides, as shownin Fig. 3, and being thus formed it will operate toprevent the fuel from spilling over the edge of the grate when being opera-ted. y The grate Gr is made with its forward half, G1, longer than its rear half, G2, from its central pivot c, so that its front edge will project beyond the outer edge of the fire-pot at the opening m, as .shown in Fig. 3.

Being thus constructed and arranged beneath or in the lower portion of the nre-pot, the said grate will afford the same facility for being shaken and dumped, while its front portion will be made to act as a projecting shelf for holding any fuel that may be inclined to pass out of the opening x, and will preserve the saine from being run out, which could not be effected if the front of the grate was arranged within the lirepot. The lire-pot D is placed out of the center of the stove and toward the front of the same, as in Figs. 2 and 3, while the magazine is preserved central, asV shown. The said fire-pot is suspended in the space inclosed by the wall-plate C C', and is supported by the same, as shown in Figs. l and 2. Between the said plate C at its rear and lthe outer wall of the stove is placed the vertical flue H, (shown by full lines in Fig. 2 and dotted lines in Fig. 3,) which flue H separates the semi-crescent iiues C C, located between the plate C and the outer wall B of the stove. The said side flues thus formed communicate with the side base-dues I I, Fig. l. Made in the base of the stove and in the central portion of the same is the mid-flue J, which leads from the side lues C C, and communicates with the vertical flue H, leading to the eXitlue K, Figs. 2 and 3. By this arrangement of the re-pot and the supp'ortingwall C out of the center of the stove, the fuel entering the nre-pot from the magazine will have a less depth in front than if placed central with the magazine and the stove, and will burn in thinner layers toward the front of the fire-pot, and the products of combustion will escape from the nre-pot into the said flues C G, and pass in an unobstructed manner into the side baselues I I in a sheet form, thereby highly heating the sides of the stove and the sides of the base, and will from thence pass into the mid base-nue J, and thence' enter the vertical rear flue H to escape through the exit-flue K, as indicated by arrows in Figs. l, 2, and 3.

The manner in which the several parts of this invention operates to effect their useful results is as followsr The opening w will permit the discharge of clinkers from the repot at its front, while the gradual contraction of the said opening as it passes back will prevent the larger pieces from passing out at the sides of the said opening, and the said opening will itself operate to permit a greater supply of air to the fuel, which will materially aid or stimulate its combustion in the front portion Y of the fire-pot forward of the magazine, as it is conically piled in the same. The ledge or shelf z on the inside of the fire-pot and over the opening operates to cast the fuel farther toward the center of the grate as it falls down, and thereby prevents the same from readily escaping from the said opening. The grate having its forward portion extended4 farther from the pivot on which it is shaken than its back, and ranging with the outer surface of the front wall of the fire-pot, or a little beyond the saine, will effectuallyprevent any fuel from working off the grate, and at the same time permit the grate to be declined in front when the cliukers are to be removed without the fuel readily falling past or off the front edge. The two semi-crescent sheetfines between the sides of the fire-pot and the outer wall of the stove will operate to greatly increase the heating power of the stove by the products of combustion passing down the same in an obstructed manner into the side base-fines, and in their passage impinging directly on the side walls of the stove and the base, and the mid-flue ,in the base will opcrate to draw the products of combustion from the side base-dues to enter the rear vertical flue after their heating powers have been partially spent, and in their passage the products of combustion will cause the front and side portions of the stove to become hotter and more effective for heating by radiation thanthe rear portion of the saine.

lt is to be understood that the' feature of the inclined lower end of the fire-pot sloping downwardly lfrom front to rea-r is new'in this invention; and, though it is used by me in another invention niade subsequent to this application, yet in combination with other ele` ments or means not found in this invention, and is only used in my subsequent application in the combinations therein shown.

Having described my. invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A re pot or box constructed with its lower end declining from front to rear, in coinbiuation with the horizontal grate, substantially as and for the purpose set forth.

2. A fire pot or box constructed with its lower end declining from front to rear, and with a shelf or ledge projecting inwardly from the front portion of said declining lower end, in combination with the horizontal grate, substantially as and for the purpose set forth.

3. A lire pot or box constructed with its lower end declining from front to rear, in combination with a horizontal grate having its rear portion within the fire-pot, and its front portion projecting beyond the lower end of the same in front, substantially as and for the purpose set forth.
